I accidentally changed the resolution and I can't return the old resolution, can one of the mods please change it back for me

Hi. Thank you for contacting us about your issue.
 

To change the game's resolution, click the Options tab (in the main login menu or in-game). The first option should be the Graphics tab. There, you should be able to see the Resolution option. You can then click on it and select the appropriate Resolution for you. Once it's selected, click Apply, then Ok. You should see the effects immediately but if you don't, restart the game and client.
 

Please come back to us to let us know if the solution provided was helpful. 
 

Looking forward to hearing back from you,
